HARRY A. HOUSEMAN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO STANDARDMACHINE COMPANY, OF PHILADELPHIA, PENNSYL- VAN IA, A CORPORATION OFPENNSYLVANIA.

WEB-HOLDER FOR CIRCULAR-KNITTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 781,653, dated February7, 1905,

Application filed November 18,1903. Serial No. 181,584.

Be it known that l, HARRYA. HoUsmmN, a citizen of the United States,residing at Philadelphia. county of Philadelphia, and State ofPennsylvania, have invented a new and useful lmprovement in \Veb-Holdersfor Circularlinitting Machines, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,which form a part of this specification.

ln ci rcular-knitting machines the web-holders are placed in slots inthe upper surface of the needle-cylinder, in which slots they arereciprocated. The function of the web-holder is to force the cast-offstitch into the needlecylinder, and thus take it away from the line ofthe needles and hold down the goods to prevent them from rising with theneedles. if the web-holder in its reciprocation extends beyond the innerperiphery of the needle-cylinder, the material as it passes from theneedles strikes the end of the web-holder, which tends to damage thegoods. The web-holders, however, must be given a sutiicient movement toenable them to perform their proper functions. The ditticulty with thepresent construction of web-holders is that if the forward throw be suchas not to project the web-holder beyond the inner periphery of theneedle-cylinder and yet give sufficient throw to enable the web-holdersto perform their function in th rearward movement there is a tendencyfor the web-holders to pass beyond the outer periphery of the cylinderand on the return movement to strike the cylinder.

in my improved web-holder 1 construct the forward end of the web-holderon an incline or bevel, so that with the necessary throw while in theforward movement the lower end will pass beyond the inner periphery ofthe cylindersubstantially all the remainder of the end will still bewithin the slot and not touch the goods, while in the rearward movementthe lower end will not pass beyond the outer periphery of theneedle-cylinder, and thus the web-holder reciprocates or moves withcertainty without contacting with the goods.

i. will now describe my invention as illustrated in the drawings, inwhich Figure 1 is a side view of my improved web-holder. Fig. 2 is asectional view of needle-cylinder, showing a needle and the webholder inits forward position. Fig. 3 is a view similar to Fig. 2, showing theweb-holder in the rearward position.

A is the needle-cylinder having the needles (1. .In the upper surface ofthe needle-cylinder are the slots 1. for the web-holder B. Theweb-holder B is provided with the forward inclined or beveled end I),terminating in the horizontal ledge I), having the slot end 6". Thestitch is drawn upon the ledge I! when the web-holder is in the positionshown in Fig. 2 and is cast therefrom when the web-holder is in theposition shown in Fig. 3.

Referring now to Fig. 2, it will be seen that with my improvedweb-holder the forward throw may be such as to project the lower forwardend of the web-holder beyond the inner periphery of the needle-cylinderand yet leave substantially all of the remainder of the end within theslot. in the rearward movement, Fig. 3, while the upper forward end ofthe web-holder B passes beyond the outer periphery of theneedle-cylinder the lower forward end is still within the slot, so thaton the next forward movement of the web-holder it is properly guided andwith no danger of the lower forward end in the rearward movement passingbeyond the outer periphery of the needle-cylinder, and thus tending notto return to the slot in the forward movement.

llaving now fully described my invention, what I claim, and desire toprotect by Letters Patent, is

A web-holder having a projecting portion provided with upper and lowerhorizontal edges connected at their forward ends by an inclined orbeveled edge.

In testimony of which invention 1 have hereunto set my hand, atPhiladelphia, on this 13th day of November, 1903.
